We all know how much Mariah Carey loves Christmas. Just take a look at all the holiday albums she has released over the years. The American Idol judge joined pop’s reigning prince Justin Bieber on stage at Rockefeller Center for NBC’s annual Christmas tree lighting ceremony. Mariah wore a red sparkling tulle skater dress embellished with silver sparkles, paired with long over-the-elbow red gloves.

But what’s a holiday celebration without a quick outfit change? Mariah also rocked a Billie Holiday-esque silver sequin off the shoulder gown equipped with a fur shawl, to keep her singing pipes warm of course! She even added a white flower in her hair to complete the look.
